When the cover 2 is attached to the main body 1, the skirt portion 21 covers almost the entirety of the circumferential wall 112 and a part of the circumferential wall 122 of the main body 1 in a direction perpendicular to the height direction (direction z) of the main body 1. (That is, the cover 2 covers
The cover 2 is configured to fit to the upper portion of the main body I. The cover 2 includes a ceiling portion 20 that is an upper portion of the cover 2, and a skirt portion 21. The ceiling portion 20 is generally elliptical in plan view. The skirt portion 21 extends generally downward from the periphery of the ceiling portion 20.
When the cover 2 is attached to the main body 1, the ceiling portion 20 covers the top wall 121 of the main body 1 with a predetermined gap interposed therebetween in the height direction of the main body 1 (direction z) . The ceiling portion includes a recess 201, an inner ridge 202 and an outer ridge 15 203. The recess 201 is formed at the upper surface of the ceiling portion 20 and annular (generally elliptical in this embodiment) as viewed in the height direction of the main body 1 (direction z) . The inner ridge 202 is a raised portion positioned on the inner side of the recess 201 as viewed in the height direction 20 of the main body 1 (direction z) . The outer ridge 203 is a raised portion portioned on the outer side of the recess 201 as viewed in the height direction of the main body 1.
As better shown in Figs. 6 and 7, in the vertical cross section containing the central axis Ox extending in the vertical direction (direction z) , the recess 201 has a curved contour.
As described above, the bulge 111a at the bottom wall 111 of the main body 1 is configured to be received in the Iecess 201.
In this regard, the bulge 111a also has a curved contour in the vertical cross section containing the central axis Ox. The shape of the bulge 111a in this vertical cross section generally conforms to that of the recess 201.
When the cover 2 is attached to the main body 1, the skirt portion 21 covers almost the entirety of the circumferential wall 112 and a part of the circumferential wall 122 of the main body 1 in a direction perpendicular to the height direction (direction z) of the main body 1. (That is, the cover 2 covers
6 a part of the side of the main body 1.) The skirt portion 21 has an inner circumferential surface formed with a plurality of engagement projections 211. The engagement projections 211 are configured to engage with the engagement groove 17 of the main body 1. The lower edge of the skirt portion 21 has cutout portions 212 that are retreated upward. When the cover 2 is attached to the main body 1, the extensions 128 of the main body 1 are received in the cutout portions 212, whereby the posture of the cover 2 in the attached state is maintained.
Further, when the cover 2 is attached, the engagement broj ections 211 of the cover 2 engage with the engagement groove 17 of the main body 1.
The cover 2 having the above-described structure may be made of a synthetic resin having a certain strength as a single unit.
The use and advantages of the metal parts attracting holder A having the above-described structure are described below with reference to Figs. 8-12.
In use of the metal parts attracting holder A, as shown in Fig. 8, just putting the metal parts N such as sewing needles or dress pins on the top wall 121 of the main body 1 causes the metal parts N to be instantaneously attracted to and held on the attracting surfaces 125, 126 due the magnetic force of the permanent magnets 15 and 16 contained in the main body 1.
Due to the arrangement of the two permanent magnets 15 and 16, all the metal parts N lie across the groove 127 and generally in parallel to a line connecting the two permanent magnets 15 and 16 to each other. Moreover, since the groove 127 is provided, the user can easily pick up a desired metal part or metal parts N with fingers.
A plurality of metal parts attracting holders A may be used to hold different types of metal parts N as classified.
